Which scientific field is involved in the identification, classification, and naming of organisms?

• A. Pathology
• B. Taxonomy
• C. Nomenclature
• D. Epidemiology

Answer: (B)

Taxonomy is the science that identifies, classifies, and names organisms. It begins with recognizing what organism you’re looking at and describing its characteristics to determine its identity. Then it places that organism into a hierarchical framework—grouping related forms into categories such as genus and species based on shared traits and evolutionary relationships. Finally, taxonomy assigns the formal scientific name to the organism using standardized rules, so every species has a unique, universally accepted name. While nomenclature handles the naming rules themselves, taxonomy covers identifying and classifying as well as naming, which is why it best fits a question asking about all three activities. The other fields don’t encompass the full scope: pathology focuses on disease processes, epidemiology on disease distribution in populations, and nomenclature alone is limited to naming conventions rather than the identification and grouping of organisms.
